| the phytopathogen dickeya dadantii (erwinia chrysanthemi 3937) is a pathogen of the pea aphid. | dickeya dadantii (erwinia chrysanthemi) is a phytopathogenic bacterium causing soft rot diseases on many crops. the sequencing of its genome identified four genes encoding homologues of the cyt family of insecticidal toxins from bacillus thuringiensis, which are not present in the close relative pectobacterium carotovorum subsp. atrosepticum. the pathogenicity of d. dadantii was tested on the pea aphid acyrthosiphon pisum, and the bacterium was shown to be highly virulent for this insect, either ... | 2006 | 16517643 |
| participation of a galactose-specific c-type lectin in drosophila immunity. | a galactose-specific c-type lectin has been purified from a pupal extract of drosophila melanogaster. this lectin gene, named dl1 (drosophila lectin 1), is part of a gene cluster with the other two galactose-specific c-type lectin genes, named dl2 (drosophila lectin 2) and dl3 (drosophila lectin 3). these three genes are expressed differentially in fruit fly, but show similar haemagglutinating activities. the present study characterized the biochemical and biological properties of the dl1 protei ... | 2006 | 16475980 |
